Assembler

symbol is any alphanumeric text starting with an alphabetic character, a number, or an expression.

Examples:

SYM1	EQU	(12 * 256)
SYM2	EQU	SYM1	*	(32	/ 4)
SYM3	EQU	SYM1	*	SYM2 ± *0x200

From the above example SYM1, SYM2 and SYM3 are symbols for some ex- pression. The grammar for Symbol is as follows:

symbol: expression

symbol

Expression Restrictions: It is recommended that a space be inserted between the operator (i.e., +, ±, *, /, , &) and the symbol or numeric expression to perform arithmetic and bitwise operations. For example ADD A0, A0, 1

+±2, adds a ±1 to A0, because the argument is read as 1+(±2) = ±1; but writing the argument as 1+±2 may or may not give the correct result. Outside parenthesis are not allowed in instruction arguments. For example, ADD A0~,A0~,(1 + (2 * 300) ± 256) causes compile time syntax error. But removing the outside parenthesis i.e., ADD A0~,A0~, 1 + (2 * 300) ± 256, causes no error.

#ELSE: see #IF and #IFDEF

#END_FT : This directive is created by the C± ± compiler when it outputs assembly code to a file. It marks the end of the function table used to track function calls and C± ± variables in the emulator. Users should NEVER use

this directive in an assembly language program.

#ENDIF: marks the end of a conditional assembly structure started by #IF or

#IFDEF

#IF expression: Start of a conditional assembly structure expression is an

arithmetic expression that can contain symbols. Caution: since the conditional assembly is resolved during the first pass of the assembler, no forward referenced symbols should be used in a conditional assembly expression. If an expression is TRUE (non zero), then the lines following this directive are assembled until a #ELSE or a #ENDIF directive are encountered. If an expression is FALSE (equal to zero), then all input lines are skipped until a #ELSE or a #ENDIF directive are encountered. If a #ELSE directive is encountered first, all lines following it are assembled, until a #ENDIF directive is found.
